Structural assessment of roadway bridges is great of importance due to the advanced development of transportation and heavier moving vehicles. In this study, improved closed-form solutions for the vibration behavior of thin-walled beams subjected to the motion of a heavy vehicle are proposed. Initially, the developed governing coupled differential equations of thin-walled beam motions are established for vertical, lateral and torsional directions rooted in the Vlasov and Euler-Bernoulli theories of beams. In practice, a moving vehicle crossing a bridge can also produce harmonic vertical and la...
